	 * xml2array() will convert the given XML text to an array in the XML structure.

	 * Arguments : $contents - The XML text
	 *                $get_attributes - 1 or 0. If this is 1 the function will get the attributes as well as the tag values - this results in a different array structure in the return value.
	 *                $priority - Can be 'tag' or 'attribute'. This will change the way the resulting array sturcture. For 'tag', the tags are given more importance.
	 * Return: The parsed XML in an array form. Use print_r() to see the resulting array structure.
	 * Examples: $array =  xml2array(file_get_contents('feed.xml'));
	 *              $array =  xml2array(file_get_contents('feed.xml', 1, 'attribute'));
